Stackably is a point of sale built for quick-service and counter-service food businesses. It gives a restaurant everything it needs to build a menu, take orders at the counter or on a handheld, send tickets to the kitchen on printers or a kitchen display screen (KDS), accept payments, and receive online and delivery-app orders, all on Sunmi hardware running Stackably POS.

Stackably is deliberately focused on quick service. It is a great fit for counter ordering, pickup, delivery and fast casual. It does not offer table management, table maps or seat-based ordering, and it is not a fit for full-service restaurants (see Who Stackably Is For and What's Not Included below).

The Stackably software is free. Merchants pay for hardware and optional services, such as delivery app integrations or a backup internet SIM card, plus the $10 per month Ubiquiti network when their setup requires it (see Network and Internet), but there is no software subscription fee.

Stackably works with any combination of the devices below. There is no fixed bundle: a merchant can have one device or many, and all devices work together on the same account.

Hardware is provided for a monthly fee per device. Current fees for each device are shown during the application process, and the merchant's agent will confirm the hardware and pricing with the merchant. Hardware is not currently available to purchase outright. When the setup needs the Ubiquiti network, it appears on the proposal as its own $10 per month line rather than being built into the price of the printer.

All devices on a merchant's account sync with each other through the cloud. An order started on a P3H handheld appears instantly on the T3 at the counter and can be checked out there, and an order rung up on the T3 can be opened and edited on a handheld. Kitchen tickets can be sent from any device to any kitchen printer or kitchen display screen.

When a merchant's setup includes a printer in the kitchen or away from the counter, or a kitchen display screen (or several networked devices, such as multiple P3H handhelds), Stackably ships a pre-configured Ubiquiti network along with the hardware.

Merchants can add a SIM card to the network for $20 per month. If the restaurant's internet goes down, the network automatically switches to 5G cellular service, usually within 30 to 120 seconds, and all devices, kitchen printers and kitchen display screens keep working. Cellular service may be slower than the primary internet, so staff may see brief loading screens, but orders and payments continue. The SIM card is set up by Stackably before shipping.

This backup is recommended for restaurants where downtime would be costly. For a full explanation of the network, its cost, when additional networking is needed, the 5G backup, SIM cards in terminals and how these differ from offline mode, see Networking at Stackably.

Stackably requires an internet connection. There is currently no offline mode. The 5G backup is the recommended way to stay running during an internet outage. Offline mode is in development.

Each item on the menu is a product with a name, price, category, and description. Products can be assigned to print at specific kitchen printers or appear on specific kitchen display screens. Packaged items can be added by UPC: enter or scan the barcode and Stackably automatically fills in the item name, description, and SKU and offers product images to choose from. The merchant then sets the price and category.

A variant is a different version of the same item, each with its own price. For example, a burger sold as single or double, or a drink sold as small, medium, or large. When the item is ordered, the POS first asks which variant the customer wants.

Modifiers change or add to an item, such as cooking temperature, sides, sauces, or add-ons. Each modifier group can be configured with:

The POS walks staff through each required choice and will not let them continue until required selections are complete. Optional groups can be skipped.

Variants vs. modifiers: a variant changes what the item is (a different size or version), while a modifier changes what is done to the item (how it is cooked or what is added). The help center article "Variants vs. Modifiers" explains this in detail, and the article "Complex Restaurant Menu Item Example" (search "surf and turf") walks through building a multi-step item step by step.

Merchants can create menus with time-based availability, so certain items or specials are only available during set hours (for example, breakfast, lunch, or happy hour).

Menu items can carry a Recipe Map that lists the ingredients they use, including ingredients tied to a modifier option, so ingredient stock is deducted as items are sold. Recipe-type bills of materials, costing reports and a waste log are available for merchants who want ingredient-level inventory. See the help center articles on Recipe Map and Bills of Materials.

Quick-tap "hot buttons" such as No, Light, Regular, or Extra (for example, "no onions" vs. "extra onions +$0.50") are in development. Until they are released, these can be set up as modifier options, which works but takes more setup.

The Stackably team builds the merchant's menu as part of setup. Stackably has internal tools, including AI-assisted menu conversion, to import complex menus quickly and accurately, then reviews them before they go live. Agents or merchants may build the menu themselves if they prefer, but one party should own the menu build to avoid conflicting changes. Either way, Stackably reviews the finished menu with the merchant and confirms they are happy with it before any hardware ships.

Stackably supports dual pricing (separate cash and card prices). The POS displays the cash price and card price for every item and for the order total, and automatically applies the correct price based on how the customer pays. The receipt shows the final total rather than a separate fee line.

Compliance requirement: to run dual pricing compliantly, the merchant's menu must show both the cash and card price anywhere prices appear, including printed menus, menu boards, and online menus. A sign at the door or register on its own is not enough. Stackably does not currently offer a service for reprinting menus with dual prices; merchants are responsible for updating their printed menus. See the help center article on dual pricing compliance for full details.

Stackably includes a built-in online ordering flow. Merchants can share a link so customers place pickup orders directly with the restaurant, without going through a third-party delivery app. Online orders come straight into the POS.

Stackably offers a native integration with DoorDash, Grubhub, and Uber Eats for $45 per month. Orders from these apps flow directly into the POS, and the menu is managed in Stackably: when the merchant changes their menu in Stackably, it updates on the delivery apps.

Important for merchants with existing delivery app integrations: because Stackably manages the menu, any existing delivery app setup will need to be reconnected or rebuilt so it syncs with Stackably. In most cases the merchant's current integration is replaced, and their delivery app menus will be rebuilt from their Stackably menu. The Stackably team will walk the merchant through this.

An option for merchants to dispatch their own delivery orders through a third-party driver network, without customers using a delivery app, is in development and not yet available.

Stackably supports tabs and card pre-authorization. However, bars and tab-based setups are not being onboarded yet while training materials and support resources are finalized. Bars are expected to be a strong fit because they typically run from the counter rather than from tables, and onboarding will open soon.

No on-site installation is required for most locations. Setup is handled remotely with a high-touch, white-glove approach. Locations that need additional networking or onsite cabling are quoted separately.

Is there a monthly software fee?
No. The Stackably software is free. Merchants pay monthly fees only for hardware and optional services such as the delivery app integration ($45/month) or the 5G backup SIM card ($20/month), plus the Ubiquiti network ($10/month per location) when their setup requires it.

When does a restaurant need the $10/month network?
Whenever a printer is in the kitchen or anywhere away from the counter terminal, and whenever a kitchen display screen is used. A printer at the counter beside the terminal does not require it on its own. Some locations, such as a kitchen far from the counter or a large space, need additional networking at an additional cost, quoted per location.

Can products be added from the terminal?
Yes. Products can be added and managed from the POS as well as from the Stackably dashboard.

Can staff take orders away from the counter?
Yes. The P3H handheld can be used to take orders and payments in the queue, at an event or at a food truck window, with an optional hand strap and charging cradle. Orders sync to every other device and go to the kitchen printers or kitchen display screen.

Does Stackably support table management or full-service restaurants?
No. Stackably does not offer table maps, table management, seat-based ordering or order and pay at the table. It is built for quick-service and counter-service restaurants. Full-service restaurants that need table management are not a fit.

Do merchants need a KDS?
No. Merchants can send kitchen tickets to networked kitchen printers, to a kitchen display screen (KDS), or to both. Many quick-service kitchens run on printers alone; assembly-line kitchens usually prefer a KDS.

Does the merchant need to cancel their current DoorDash, Grubhub, or Uber Eats integration?
In most cases the existing integration will be replaced or rebuilt so that the menu syncs from Stackably. The Stackably team will help with this transition.

Is a sign at the door enough for dual pricing?
No. Both the cash and card price must appear on the menu wherever prices are shown.

Who builds the menu?
Stackably builds it by default and reviews it with the merchant before shipping. Agents or merchants can build it instead if they prefer, but one party should own the build.

What happens if the internet goes down?
Without a backup, the POS will not work until the internet is restored, as there is no offline mode yet. With the optional 5G SIM card backup, the system switches to cellular service within 30 to 120 seconds and keeps running.

Does someone need to come on site to install the system?
Usually not. Hardware arrives pre-configured and networked. The merchant plugs it in, and Stackably confirms everything by phone and walks them through the software. If a location needs additional networking or cabling, that onsite work is quoted separately.

Who makes the hardware?
Stackably uses Sunmi devices. Sunmi is one of the largest POS hardware manufacturers in the world and has supplied hardware to major POS providers.

Who processes payments?
Payments are processed through TSYS.
